9 Ways Animals See The World Differently

[@Gus-tw7zw]

SciShow is the common mans science channel and I love it. You go through day to day interesting things and don't swamp us with too much technical jargon. This is the kind of thing I can show to a kid to get them interested in science yet still be interested myself.

"I am Not performing for you~ ~Air sucking,bog eyed,ugly,arrogant, nasty,mutated, morally bereft,weaklings!! -Now,put me into my beautiful natural home!"

[@RMoribayashi]

Humans with extraordinary vision also exist. The most common male color-blindness is caused by having the red cones mutate to be centered too close to the same light as green cones. Sisters of men with this type of color-blindness occasionally inherent both normal red cones from their father and mutated ones from their mother, giving them *_four sets of cones_* instead of the usual three, making them true tetrachromats. Achromatopsia, a particularly rare form of colorblindness where sufferers have no color sensing cones at all affects 10% of the population of the Micronesian island of Pingelap. These people are so sensitive to light they are nearly nocturnal. Their extraordinary night vision is sensitive enough to let them take their boats fishing in near total darkness. Our retinas can sense the near-ultraviolet, but our lenses are opaque to it and block it. Impressionist Claude Monet had the lens of his right eye removed (an early type of cataract operation). After he recovered, his paintings were suddenly dominated by blue. Many have suggested that the operation gave him the ability to see blurrily into the near ultraviolet while he used his still clouded left eye to see detail.

[@TheRABIDdude]

Fantastic little facts, thanks!! It would be good if you rephrased the second sentence, about red-green colour blindness, though. E.g. to "A mutation in one of pigment genes causes the red and green cones to be stimulated by very similar wavelengths of light."

the amount of people who have never used an RGB based software is too damn high! BTW explanation to try and prevent future comments: Primary colors for light emitters (aditive - the sun, a lamp, this display): red, green and blue. Primary colors for light absorbers (subtractive - paint): cyan, magenta and yellow (cyan and magenta are sometimes simplified to blue and red because they are lighter shades of these). Fun fact: if you combine RGB lamps, you get white (they sum up). if you combine CMY ink, you get black (they block each other).

Horizontal pupils increase a goats peripheral vision so they can watch out for predators. And to prevent the pupils from turning vertical while they graze, they have evolved the ability to rotate them to keep them parallel to the ground.

The more I learn about nature the less special I feel we as humans are and the more animal I feel. The more I feel part of this greater natural world. We are not special and "animals" are not beneath us or lesser in any really significant way. Sure our brains are spectacular evolutionary creations but we share so much more in common with our animal brothers than we like to think. It's a comforting thought for me.

[@CountBrennuvarg]

+〈Insert name here〉 It'd be like trying to describe an image to someone who's been blind their whole life.

[@georgelaidlaw3748]

+Haku infinite Nope. We have no reason to think that an insect's brain processes and renders each image from each lens as its own seperate image of the world. In fact, given everything we know about how visual information is processed, we have reason to believe that flies, like everything else, stitch together the data from each ommatidia into a single pixellated blurry image that functions much like human peripheral vision (great at detecting movement, relative position and sudden changes but rubbish for fine detail).

Yeah, it's complicated. Imagine trying to make a picture that your cat can look at to see what you see when cats are limited to fewer colors! How do you make the picture more colorful for them??? Similar problem whenever translating within our own limits.

[@joshuaosei5628]

We don't know all of them.... If they did some, they'd have to do all of them.

[@the1exnay]

well, they simply dont know. nor could they really. consider the fly eyes, oftentimes movies will show a bunch of almost the same image tiled on the screen. but that is like assuming humans see two images, i mean we do but generally we interpret it as one unified image. if you looked through a flys eye, well you wouldnt be able to understand it. but if you could see as a fly did then you would probably see one cohesive image. which may or may not have noticable curvature to it, we dont know. he mentioned that the rocky eyes resulted in pixelated images when they tested them. and that makes sense, but the animal wouldnt see it as pixelated, if he saw it at all like we do. he might process it similar to sound or something completely different.

[@RumerPriestly]

+Joshua Osei not true? A simple "we don't have enough information for an example of this animal's vision" for one or two would have been much better than no examples at all.

[@joshuaosei5628]

Rumer Priestly But that'd be a handful of them. Why have half shown and the other half not? I thought about your question, but it seems like leaving it out all together is better. Also helps us to use our imagination more :)

awesome video, very educational :)

[@LiamQ1994]

Awesome info! You should do an entire segment on chameleon eyes though, those are crazy. Chameleon eyes can not only move independently, but they perceive depth in a hell of a strange way. We use the differences in image from both our eyes to judge distance but it's difficult to do that when your eyes are looking at completely different things. For chameleons then, they have developed a strange shaped eye that focuses the image well beyond the centre of rotation of the eye, and judge the distance of an object really oddly by making small darting movements of the eye and judging the distance by how much a target moves relative to other things in the image. For example, something farther away will appear to move less distance than something in the foreground or something along those lines.
